Field G. Van Zee 09bd4f4f12 Add err_t* "return" parameter to malloc functions. ...

Details:
- Added an err_t* parameter to memory allocation functions including
  bli_malloc_intl(), bli_calloc_intl(), bli_malloc_user(),
  bli_fmalloc_align(), and bli_fmalloc_noalign(). Since these functions
  already use the return value to return the allocated memory address,
  they can't communicate errors to the caller through the return value.
  This commit does not employ any error checking within these functions
  or their callers, but this sets up BLIS for a more comprehensive
  commit that moves in that direction.
- Moved the typedefs for malloc_ft and free_ft from bli_malloc.h to
  bli_type_defs.h. This was done so that what remains of bli_malloc.h
  can be included after the definition of the err_t enum. (This ordering
  was needed because bli_malloc.h now contains function prototypes that
  use err_t.)
- Defined bli_is_success() and bli_is_failure() static functions in
  bli_param_macro_defs.h. These functions provide easy checks for error
  codes and will be used more heavily in future commits.
- Unfortunately, the additional err_t* argument discussed above breaks
  the API for bli_malloc_user(), which is an exported symbol in the
  shared library. However, it's quite possible that the only application
  that calls bli_malloc_user()--indeed, the reason it is was marked for
  symbol exporting to begin with--is the BLIS testsuite. And if that's
  the case, this breakage won't affect anyone. Nonetheless, the "major"
  part of the so_version file has been updated accordingly to 4.0.0.
